TOGGLE-BOLT.

Specification of Letters Patent.

Patented Nov. 12, 1907;

Application filed December 22. 1902. Serial No. 136.202.

To all whom it may concern:

lie it known that I, AtvInUs L. ELLIS, a citizen of the United States, residing at Ulric-ago, in the county of Cook and State of Illinois, have invented a certain new and useful improvement in Toggle-Bolts, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

M y invention relates to improvements in toggle bolts. In view of the extensive use of such bolts to secure various things to hollow tiling of which the walls of lireproof buildings are generally constructed, 1 will describe my invention as thus applied. But it must not be understood, however, that I limit myself to said use, for the purposes and instances in which my improvementunay be employed, are varied.

The invention in its preferred embodiment consists of the details of construction, arrangement and corribination of parts as hereinafter described and particularly pointed out in the claims:

In the accompanying drawings, Figure l is a sectional view taken through a wall, constructed of hollow tile, showing my improved bolt applied to secure inposition a molding for electric wires; Fig. 2 is a similar view showing the bolt before it is tightened, and. in. dotted lines; the position of the bolt just after the toggle has been put through the hole and before it has swung into its normal position; Fig. 3 is a view of the bolt with the toggle in section; Fig. 4 is an end 'view of the construction shown in Fig. 3; Fig. 5 is a so that the toggle may swing on its pivot into its normal position; Fig. 7 is a view of the inner end of a bolt with the toggle adapted to be inserted in a vertical position showing particularly how the toggle is held by the stop at such an incline that it will fall by the action of its weighted end into the position indicated in dotted lines; Fig. 8 is a detail view of a bolt having a smooth pin to which the toggle is adapted to be clamped; Fig. 9 is a view of a modification of my improved .construction; Fig. 10 is a view of a belt of the construction shown in Fig. 9 employed to secure a molding for electric wires to a tile wall; and, Fig. I1 is still another modification of my invention.

Throughout the drawings, like reference characters designate similar and corresponding parts.

Referring now to the drawings which only show the preferred embodiment of my invention, a, preferably, screw-threaded pin 2, has, preferably, screw'threaded thereto a suitable head 3. Also, preferably, screwthreaded upon said pin, is a nut 4 to which is pivoted a toggle 5. The toggle is, preferably, constructed of a plate having its longitudinal edges bent up. Said plate is provided with a hole 6 to receive the pin 2, and between its up bent edges is supported a pivot 7 which turns in a hook 8 formed on the nut 4.

For the purpose of illustrating the application of nry improved toggle bolt, I have shown in Figs. 1, 2 and 10 a broken section of a wall which is constructed of hollow tile 9 over which is plaster It). A hole 11 leading to the interior of the tile, is shown to receive the toggle bolt, and a molding for electric wires is indicated as the thing to be supported by said .toggle bolt. When it is desired to place a bolt of my improved construction in position, the pin is withdrawn from the hole 6 thereby permitting the toggle to be turned on its pivot into the position shown in Fig. (5. The outer end 12 of the toggle is preferably, weighted so that when said toggle is arranged below the pin 2, as in Fig. 6, the inner end thereof will bear up against said pin, and thus said toggle will remain in a position adapted to its insertion through the hole 1 l into the tile 9. So that the toggle may be moved into the position indicated in dotted lines, by turning the pin 2, said pin is, preferably, upset, as at 13, whereby said pin may be screwed so that said upset end will cause said not to sufficiently frictionally engage said pin to insure the turning of said toggle with the pin. After the toggle has been passed into the interior of the tile and turned into the position indicated in dotted lines in either Figs. 6 or 2, it is evident how the weight, which before held the toggle in a position to be inserted, will now exert its force to bring the toggle into a position transverse of the pin as shown in full lines in Fig. 2, whereby said toggle will engage the inner wall of said tile and prevent the withdrawal of the bolt. In this position the bolt may be tightened until it secures in place the article which it is desired to support. The bolt may also be removed as easily as it was inserted. First the pin is unscrewed until its end is withdrawn from its hole in the toggle, and the upset end of said pin binds in the nut. The toggle may then be rotated into any position by turning the pin. When the pivot for the toggle is rotated into a position below the pin, the said toggle will fall, if moved out from the inner wall of the tile, into such position that the bolt may be readily withdrawn.

The toggle is provided with a stop 14, preferably struck up from the plate from which the toggle is formed. This stop is intended to prevent the toggle from turning so far on its pivot that the weight would not cause the toggle to fall into proper position when desired. In Fig. 7 it is very clear how, if it were not for the stop 14, the weight for extending the toggle would be on the wrong side of the center of gravity, and therefore, fail to operate said toggle.

It will be noted, that by means of the head of the bolt being removable, it is only necessary to provides. hole in the article to be secured of the same size as the pin. The construction of the parts of my bolt is simple and cheap of manufacture, and said parts may readily be assembled, or separated one from the other. In all, I have provided an efficient device which may be handled with facility. Moreover, with my improvement the unfinished appearance necessitated by the use of toggle bolts as heretofore constructed, will no longer be present, and as neat anappearance may be effected with my device as might be obtained with nails, screws, nuts, bolts, etc., which do not require toggles to hold them inposition.

While in the preferred embodiment of my invention a screw threaded pin is employed, yet a smooth pin, as illustrated in Fig. 8, may be used. The nut, which might in this instance be more accurately designated, a clamp, will cooperate with the toggle as a clutch and grip the pin 2. Said clutch will permit the toggle to be moved on the pin toward the head of the bolt, but not in the opposite direction without first being released. It would be almost impossible to remove a bolt of this construction after it has been put into place without considerable inconvenience or destruction of the bolt. Therefore, I, preferably use a pin screwthreaded to the nut, as such construction enables the removal of the bolt with facility and without destruction. Of course, the clutching action between the toggle and the pin is present even though the pin is screw threaded, but the toggle may be moved along the pin in either direction as the screw threads continuously operate to release the clutch when they are turned.

In Figs. 9 and 10 is shown a modified form of my invention which is particularly intended for use in places where it is not likely that it would ever be desired to remove the bolt. It is a device of obviously cheaper construction than either of these before described, and containing many of the advantages thereof. An 0rdinary wood screw 15 is used in this construction for the pin 2. The toggle 16 is made from a metal plate with its longitudinal edges bent up, like the toggle of my preferred construction, and is provided with a hole 17 for the screw. At each end of said toggle are, preferably, riveted two springs 18, one on top of the other. The free ends of said springs project over the edges of the hole 17 and are adapted to grip said screw when it is passed between them and thereby prevent the withdrawal of said screw. In setting this construction of toggle bolt in position, a cord 19 is first secured to the toggle, preferably, by passing it through holes 20 in the bent up edges thereof. The toggle is afterwards put through the hole 11 in the tile and held in position by the cord from the outside. The screw is then passed through the molding shown for electric wires, and pushed through the hole in the toggle and between the springs 18. Should the bolt be only loosely clamped in position by pushing the screw into the toggle, it may be tightened by turning said screw.

Fig. 10 illustrates the preferred manner of securing an electric wire molding in position. The head of the bolt is countersunk in the under face of the molding and the cover is placed over the end of the bolt so as to hide the head from view. The cord for holding the toggle in position while the bolt is being set, isdrawn out on one side of the molding from beneath the same, and cut off.

The construction shown in Fig. l]. is that of another form of toggle. It consists of inclined legs 21, which are, preferably, bent longitudinally for strength. At their approached or adjacent ends they are united, and a hole for the pin of the bolt, is provided in the plate 22 which connects said legs. Said legs and their connecting plate are all, preferably. formed from a single stamping. Also, stamped integrally with said plate 22, are lugs 23 which are bent/over a nut 24 upon the plate and thereby secure said nut in position on the plate. Into said nut is intended to be secured a threaded. pin

which with a suitable head, constitutes the remainder of this form of toggle bolt. In passing a toggle bolt of this construction through a hole, the outer ends of the legs are drawn together around the pin. Said legs in this position have a tendency to spring out, and therefore, when they are freed in the interior of the tile, they will spread and thereby engage the inner wall of the tile and thus prevent the withdrawal of the bolt. By screwing the pin into the nut the bolt will be bound securely in position.

Various modifications may be made in the construction which 1 have herein shown and described, without in any way departing from the spirit of my invention and the same yet remain intact and be protected.

It will be understood that the toggle need not be pivoted upon a journal as shown in the preferred embodiment of my invention, but may be pivoted to the plate in the manner shown in Figs. 9 and 10.
